intel edison compute module stuck at boot up

[VGopa2]

Hi all,

I am working on a project with Intel Edison compute module with image 3.10.17-poky-edison+ . At times i see that the device is stuck on boot up at "Starting Kernel..." . Sometimes the booting hangs at *** Ready to receive application ***. We tested it with both battery and power supply.

Note: The edison is mounted on a custom made board. If you want i can give the details.

Case 1: This doesnt loop, but is simply stuck
